CENTER OF HYDRO-ELECTRIC POWER RESOURCES IN JAPAN 

(Ref. Map I ac II) 



HE economic situation surrounding the natural fuel resources of Japan in 
relation to the present and future industrial expansion along manufacturing 
lines — the question of fuel reserves, the rise and increasing difficult}' of 
labor problems, combined — give the essential factors which have resulted in 
the remarkable progress made in the past few j^ears in hj'dro-electric development. 
In the more than three thousand miles of the mainland extending from north to 
south there are man}' rivers having suitable gradients for hydro-electric develop- 
ment, and the rainfall which is evenly distributed over the whole country assures 
a regular supply of energy in these streams. Moreover the national practice of 
forest conservancy carried out since Feudal times assures the sources and guarantees 



with the passing of time further and further improvements in their run-off and 
control. It is therefore only natural tliat these factors should quicken a rise of 
significant lij'dro-electric power development whicli must be considered to be nothing 
but an execution of the economic state policy carried out bv the " Countrj- of 
Rivers." 

The central portion cf the mainland, the heart of Japan, has many rivers of 
sharp gradient rising in the plateau of the so-called "Japan Alps." These rivers 
are so advantageously situated with reference to the demand for electrical energj' 
of large cities and towns that the}' naturally select themselves for primary con- 
sideration in the development of h^-dro-electric energy. 

Suppose we describe a circle of 75 miles radius with the center at Mount 
Ontake, 75 miles northeast from Nagoj-a, the circle embraces the central portion of 
the mainland including all the important rivers and basins capable of hydro-electric 
development. This is the reason why we call this portion of the mainland the 
" Source of Hydro-Electric Power in Japan." This source of power development 
stands close to the principal power markets of the countrj', and a circle having 
the same point as a center but of 150 miles radius which is easily within the 
present transmission distances includes practicalh' all the more important centers 
of power demand. Thus, on the east we have Tokyo, the capital of Japan, 
Yokohama and their surrounding districts, on the south Nagoya, Hamamatsu. 
Yokkaichi, Gifu, Toyohashi, Shizuoka, Nara and their environs, on the west Osaka, 
" The Manchester of Japan," Kj'oto, Kobe and their localities. It will therefore be 
noted that most of the great cities and towns of the country are included within 
this circle which could be aptly termed the industrial sphere of Japan. 

Tlie Daido Electric Power Co. together with its associated companies under 
the able leadership of President Fukuzawa has for its purpose and considers it a 
dut}- to develop and make available to the principal centers of our countrj' this 
vast source of potential and lasting wealth to the end that our growing industries 
may prosper and compete successfully in the markets of the world.

OUTLINE OF THE ORGANIZATION 

HE following outline describes in general the history and property of the 
organization together with the relation between the Daido and the Toho 
Electric Power Co. 



HISTORY 
The present Daido Electric Power Co. is the result of a combination of 
The Kiso Electrical and Industrial Co. established in 1918 with a capital of 
¥18,600,000, The Osaka Transmission Co. established in 1919 with a capital of 
¥20,000,000, and The Nippon Hydraulic Co. established in 1919 with a capital of 
¥ 50,000,000. Mr. Fukuzawa, who is now President of the Daido, was then President 
of the first two companies, and Mr. Yamamoto, now a Director of the Daido, was 
then President of the last named company. The business purpose of these companies 
was the same, i.e. to transmit power to Osaka, Kyoto and their surrounding districts 
—one from the Kiso River and the other from the northern part of the country. 




Intake, Okuwa Plant 



These prominent men in the electrical and industrial field and several other 
prominent men of business held a conference with the purpose of initiating an era 
of desirable readjustment by calling into existence a sujjer power zone in the most 
intensive manufacturing district of Japan, and it was decided in November, 1920, 
with unanimous approval to establish a limited corporation under the name of 
The Daido Electric Power Co., Ltd. 

The head office of the company is at Tokyo with branch offices at Nagoya 
and Osaka. The personell of the Board of Management and the Executive is as 
follo\vs :

There is outstanding ¥ 29,140,064 of 1% debentures. After paying interest 
on the debentures in May, 1922 there was paid 6.4?o dividend on the common 
and preferred stocks and %% additional dividend on the preferred stock. 



RELATION BETWEEN THE DAIDO AND THE TOHO 
ELECTRIC POWER CO 

The relations between the Daido and Toho Electric Power Co. of which 
Mr. Fukuzawa was for the past thirteen years President (during which time he 
carried it from practical!}- nothing to its present prosperitj') are a matter wortlij' 
of special mention. Both companies have been in close relationship since their 
establishment. 

At the time of the formation of the Daido in 1920 a mutual arrangement was 
made whereby the Daido undertook tlie dutj' of power development and trans- 
mission, and the Toho was to act as a distributing company in direct control of 
the demands of consumers. 

In the written agreement between the Daido and Toho the following clause 
occurs. 

" It is declared and also agreed that tlie Toho Electric Power Co. shall have 
the preferential right to a supplj- of electric power from the Daido Electric Power 
Co. from the power sites on tlie Kiso and Yahagi rivers which have already been 
granted by the Government and also those under application subject to the 
understanding that the Toho shall neitl.er construct power plants with the inten- 
tion of competing with the Daido nor purchase electric power from other than the 
Daido Electric Power Co." 

The relation between these two companies goes back* to the time of the 
foundation of the Kiso Electric Power & Steel Co. which developed in 1918 with 
a capital of ¥ 17,000,000, from the Nagoj-a Electric Light Co., the predecessor of 
the present Toho Electric Power Co. The Kiso Electric Power & Steel Co. was later 
renamed the Kiso Electrical and Industrial Co. and in 1920, the Daido was formed 
b\' combining this organization with two other companies. 

The distribution of the stock of the Daido held b}' the Toho and its stock- 
holders is as follows : 

Shares held by the Toho 529,150 

Shares held by its stockholders 632,440 

Total 1,161,590 

Tims more than one-half of 2,000,000 total shares are at present held by the 
Toho Electric Power Co. and its stockholders. 




ASSOCIATED COMPANIES UNDER THE DIRECTION OF 
MR. M. FUKUZAWA, PRESIDENT OF THE DAIDO 

HE distinctive feature of the Daido Electric Power Co. is the union of 
capital combining all associated companies which possess available sites 
for hydro-electric power development in well-located position with reference 
to the power market of the country. In addition to the financial com- 
bination the 
company forms a 
ring of business 
corpor a t i on s 
connecting with 
manufacturing 
and industrial 
companies such 
as electro-chemic- 
al w^orks, electric 
railways, steel 
works and other 
activities. A 
brief summary 
of the properties 
forming the com- 
bination, w^hich 
are under the 
managing con- 
trol of Mr. Fuku- 
zawa, together 
with their capit- 
alization will be 
of interest.

Power Demand Curve

Three Largest Divisions in Japan.

1911 1-2 '13 H 



SUPPLY AND DEMAND OF POWER IN CENTRAL JAPAN 

GROWING DEMAND FOR POWER 

N the mainland of Japan tliere are 31 Prefectures, including 15 large cities 
and about 200 towns. From the point of view of supply and demand of 
power, it may be divided into the following three divisions. 



Division I Tokyo, Yokohama and their surrounding districts 
,, II Nagoya and locality 

III Osaka, Kobe, Kyoto and their surrounding districts 
It is estimated that these 3 divisions will require approximately 70"o of the 
total power demand on the mainland. A statement as to the supply of power to 
these districts up to June, 1922 is : 






Steam Power

155,000 K.W. 


310,000 K.W. 


465,000 K.W. 



According to the statistical report of the Government since 1911 the annual 
rate of power demand in these 3 divisions is as follows : 

Division I 20,000 K.W. 

II 10,000 ,, 

III 20,000 „ 

Total 50,000 K.W. 

With the above ratio of annual increase of power demand, total requirements 
for each division at the end of 5 years and 10 j^ears w^ould be as follows :

Total Increase — 250,000 „ 500,000 ,, 



POWER REQUIREMENTS FOR RAILWAY ELECTRIFICATION 

A very important matter to be considered is the power which will be required 
for railw^ay electrification. The w^ork of electrifying the Imperial Government Lines 
is expected to be luider way in the very near future. It is a question whether 
the supply of power will be furnished by existing public service corporations or by 
new generating system to be built by the Government, but from the standpoint of 
sound engineering and economics there can be no doubt as to the better policy to 
invest the enormous sums of money required for separate power plants for the 
sole purpose of generating power for railway use would be folly when there are 
plants already existing capable of supplying all the power required at much lower 
cost per K.W.H. We believe therefore that the final conclusion of a careful stud}^ of 
this matter will result in the purchase of power from existing operating companies. 

The estimated power requirements for electrification of the various railroad 
sections in Central Japan are as follows :

It is expected that electrification of the railroads will be completed in 
approximately 10 j-ears, and in estimating the probable demand, consideration 
should be given to the probable increase of transportation on all lines. These figures 
show the great importance to the country of the development of hydro-electric 
power particularly in the central portion, the industrial heart of the countr}-, and 
should receive the greatest consideration from the public at large. 



ESTIMATED WATER POWER IN CENTRAL JAPAN 



According to the investigation of the Hydraulic Bureau of the Government, the 
total estimated value of the water power in the whole of Japan is approximately 
10,000,000 K. W. of which 7,000,000 K. W. is to be found on the mainland of the 
country and may be classified as follows : 

Economically applicable .... 5,500,000 K. W. 
Economically inapplicable. . . . 1,500,000 ,, 
The rivers running through the central portion of Japan, which are com- 
mercially practicable for the development of long distance transmission and have 
a combined capacity of 4,550,000 K.W. are listed with their estimated capacities 
as follows :

Of these eleven rivers all except the Kurobe, Kumano and Yodo are either under 
operation or in some stage of development. The aggregate capacity which is 
under the control of the Daido and its associated companies as shown by the

Of the total power to be developed on the Kiso river, 34,900 K.W. is now in 
operation, 110,700 K.W. tinder construction, and 118, .540 K.W. under contetnplation. 
Besides 6,000 K.W. on the Yahagi and 7,200 K.W. on the Kuzuryu are now in 
operation. According to the power hydrograph of the Kiso river, approximately 
545,000,000 K.W.H. of steady power and 440,000,000 K.AV.H. of unsteady power 
will be produced annually at the sites located on the stream above the Shizumo 
Power House. It is estimated that the total construction cost for these power 
plants on the Kiso river from Nezame to Ohi will amount to approximately 
Y 48,700,000 and the average cost per kilowatt Y ;!15. 



OHI POWER PLANT- DAM SYSTEM 

Tlic Olii Plant is intended to undcrtaki.- the sui)])ly of power for peak load 
of Osaka Sub-station, thus keeping the load of other plants such as Momoyania, 
Suhara, Okuwa and Yomikaki nearly constant. This base load will amount to 
approximately lOO.OOd K.W. 

The load factor for Ohi plant will be certainly below '){)% but the average 
load factor for all plants running together in parallel is estimated to be about 
7o?5. as the other i)lants with the exceiHion of Ohi will have naturally very good 
figures due to the nature of their loads. 

The i)re.sent work of the Daido is in the primary stage. The secondary period 
of power development on the Kiso and its tributaries will begin in the near future, 
and vi|)on its coni])lelion most of tlie power produced will be taken for base load 
at the Ohi plant. 

OTAKI RESERVOIR 

The rivers having their sources in the plateau of the 'Japan Al|)s " are usually 
low in run-off during the two winter months of January and February. The 
princij)al puri)ose of Otaki Reservoir is tf> supply water during this dry season, 
and to regulate the discharge at other times. 

The reservoir is to be constructed by a dam wall ;!()0 feet high and tlie 
capacity will be 3.200,000,000 cubic feet. The regulated flow from this reservoir 
will produce an additional 31.'0,00(),00() K. \V. H. dunng the dry season, and upon 
completion of the whole power development on the Kiso river, the total caiiacity 
of 823,000,000 K.W.H. It is e.Ki)ected that the reservoir will be completed by the 
end of 1924-. 




PROPOSED SCHEME OF POWER DEVELOPMENT 
ON THE TENRYU RIVER

At the upper end of the Tenryu river, Lake Suwa, having' a catchment area 
(jf over 208 square miles, forms a natural storage reservoir. For about 40 miles 
from Tokimata to Futamata the river flows through the great Tenrj'ii canyon, a 
place of grand scenic beauty, l)in'dered on either side by ranges of steepl}' rising 
liills {ind ])roviding sites most suitable for dam construction. 

Tile company is now ra])idly carrying" out the work of surveying, locating etc. 
This river is in striking contrast to inan\' others in that the volunie of water is 
so constant tliat the niinimuni run-off for eleven nicniths can be taken as the basis 




Part of KushiKara Transmission Line 



for power development, and no provision for steam power plants for emergency use- 
is necessar}-. If however a steam reserve is provided and the design changed to 
the eight months minimum run-off, a total capacity of 400,000 K. W. can be obtained 
with a total construction cost of ¥ 300 per kilowatt. 

It is estimated that total construction cost for these ten power plants will 
amount to approximately ¥ 87,000,000 or ¥ 34.4 per kilowatt. The Tenryu river 
is undoubtedly one i>f the finest rivers for power development in Japan.

PRINCIPAL SOURCE OF POWER DEMAND 

PRINCIPAL POWER MARKET 

NE of the most important considerations involved in the sale of power is 
location. It is a matter to which every investor should give careful 
consideration. 

Fortunately the source of hydro-electric po^ver in the central portion of Japan 




Interior VietO of Okuwa Power House 



is easily within reach of Tokyo. Yokohama, Nagoya. Kyoto, Kobe and Osaka, the 
principal power markets of the country. The following illustrations show the 
importance of our position as a supplying company with reference to the most 
intensive manufacturing centers of the country. The principal consumers are as 

follows : 

1. The Toho Electric Power Co. with Nagoya as the principal center and 
extending to Toyoliashi, Gifu. Hamamatsu, Okazaki, Yokkaichi, and Nara in the 
central district. 

2. The Osaka Electric Light Co. dealing in light and power, and other urban 




Intake Site of Proposed Mo. 4 on the Tenr;yu River 



and interurban traction companies, and industrial companies located in and near 
the cit}' of Osaka. 

3. The Kyoto Electric Light Co. which is supplying light and power in 
the city of Kyoto and the neighbouring district, and also in the Prefecture of 
Fukui. 

4. The Keihan Electric Traction Co. which carries on a traction business and 
also supplies light and power, and other industrial companies located in Kyoto, 
Osaka and their surrounding districts. 

5. The municipal government of Kobe, Kawasaki Dockyard, and other 
industrial companies located in Kobe and its environs. 

6. The municipal government of Tokyo and the Tokyo Electric Light Co. are 
the principal factors with which the Daido should cooperate in supplj'ing power 
to Tokyo, Yokohama and their surrounding districts upon completion of the pro- 
posed Tokyo transmission system. 




Part of tKe Tenrpu Canyon 



Thus the greater part of the 
power generated is delivered over 
the transmission lines to tlie sub- 
stations of the wholesale consumers 
who in turn distribute it to the 
smaller consumers.

THE FRIENDLY RELATIONS EXISTING BETWEEN AMERICAN 
MANUFACTURERS AND THE DAIDO 

Host of the cquipmetit installed in the generating stations, sub-stations, and 
transmission lines, including water turbines, generators, switch-boards, 
transmission towers, insulators, and other machinery, are of American 
manufacture. This is due to the business position gained in the world's 
markets by America as a result of the world war. The war afforded America 
tremendous op|)ortunities, as she became practicall)' the only supplier nation of the 
whole world. It also gave her citizens an opportunitj' for improvement in their 
trade methods, and manufacturers and businese men who had grown up during 
the past century with the home markets uppermost in their minds, now look to 
foreign rather than domestic business for their great opportunity. 

To date, the foreign machinery and equipment used in the construction work 
of tlie Daido, amounts to over ¥ l^, 000, 000 of which about 9U?o' is of American 
manufacture. We believe, in consequence, it is no exaggeration to say that the 
existing friendly relations between American business men and the Daido Electric 
Power Co. as well as its associated companies, will increase more and more witli 
the progress of hydro-electric development in Japan, and ^vill help to make the 
Pacific the greatest highway of commercial intercourse connecting the East and 
the West.

FUTURE BUSINESS PROSPECTS 

The jtt'ospects of the Daido Electric Power Co. Avith its natural resources and 
tceograjiliical advantages are exceptionally bright. Earl}' in 1924 the total power 
develo])cd will exceed 167,000 K. W. and the transmission system will extend 
more than 500 miles. A total number of S water |ilants and one steam plant will 
be in oj^'ration. The average construction cost for generating stations, srdj-stations, 
and transmission lines inclusive does not exceed V ."fid |,or kilowatt. It is 
exjiected therefore that \vithin two years the Daido Avill be in a position to declare 
dividends on its shares at the rate of at least 12 |)er cent. ])er annmn.
